Stock Specification

Galvoptics optical grade Silicon Windows are manufactured from Czochralski Silicon and are 99.9% pure. Uncoated, this gives a transmission band of 1.2 - 8 microns. Silicon is perfectly suited for use at 3 - 5 microns. The material has many benefits being a low cost material, perfect for weight delicate applications due to its low density and making it harder and less brittle than material such as germanium. Silicon is used for military, thermal imaging, scientific industry and substrates for optical coatings.

Our Silicon Windows are available in diameters that are uncoated or AR coated in 3-5 microns on both sides. Custom sizes and AR/DLC coating options are available on request.
